If Gas Mileage is the problem then from investigating these forums closely and a few other sites I see that the following is reccomended by some folks to ease the gas bill:

1. The K&N Air Intake - Get rid of the restrictive old box, should set you back around $220.

2. Get a Good set of spark plugs, don't skimp.

3. Tornado Fuel Saver - Available on Ebay for $40 or $50.

This not only saves on Gas mileage but will add a little more power, then for the ultimate power gain and another increase add a less restrictive Exhaust system and you should be laughing all the way to the Gas station with 3 or 4 mpg better.

Now has anyone tried any of these mods and seen an improvement? As I plan to add these to my 2000 5 speed shortly.
